ABSTRACT:
A method for making double angle V-belts is provided which comprises providing an uncured belt body, placing at least a portion of the length of such body in a mold comprising a pair of mating mold sections which, when closed, provide an elongated cavity having a double truncated V cross-section, closing the mold sections, applying uniform resilient pressure to opposite sides of the belt body while confined in the mold, curing the body portion, releasing the pressure, opening the mold and removing the resulting molded and cured belt portion.
Also provided is a mold for simultaneously molding and curing a double angle V-belt which comprises a pair of mating mold sections, each section comprising an elongated, generally symmetrical trapezoidal cavity and having means for applying resilient pressure at the apex of the cavity.
